WebbThe exhalative vents generally occur along the faults and the exhaled brine accumulates in adjacent seafloor depressions. As Sangster (2002) points out, most Sedex deposits are vent-distal. He proposes that saline fluids discharged onto the seafloor and flowed away from the vent as “bottom-hugging” fluids.

Physical … Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter).
